PS1 (7-8) – 4 Students demonstrate an understanding of states of matter by …explaining the effect of increased and decreased heat energy on the motion and arrangement of molecules. PS2 (7-8) – 7 Students demonstrate an understanding of heat energy by…explaining the difference among conduction, convection and radiation and creating a diagram to explain how heat energy travels in different directions and through different materials by each of these methods.
National Standards:
Levels 5-8: Transfer of energy.
Context of Lesson:
The reason for this lesson is to build the appropriate background knowledge in convection, conduction, and Thermal radiation to help students better understand the mechanisms of global warming.
This lesson is the first in a 10 day sequence of lessons to prepare the students for a Global Warming Project.
The next lesson in the sequence is Day 2 which is an interactive-lecture on Global Warming. This is followed by an Ice core investigation on Day 3.
This lesson is to be completed in one 50 minute block
Opportunities to Learn:
Materials:
Computer
Projector
Propane torch
metal rod
coffee cup
Stones
entrance/exit assessment
Classroom Environment:
Students will be seated in groups of four at lab tables.
Students work together in groups of 2 during entrance assessment
Independent work during exit assessment.
Cooperative Learning:
Students will be expected to work together in groups of two during the entrance assessment. They are to discusses the problem given and independently fill out and hand in their assignment.
Differentiating Instruction:
Students with a document disability will be given a similar entrance/exit assessment. However, there will be step-by-step instructions given to assist the student. Students with disabilities will also receive a print out of the class notes.
Students who are advanced or willing to try will be given a "My Science is Tight!" question. This is a question that has a higher Depth of Knowledge than the other question.
Depth of Knowledge:
Students will answer various questions throughout the class period that have a DOK of Level 1(Recall) and Level 2 (Skills/ Concept).
Objectives:
Students will be able to draw and define the difference between atoms/molecules that are “cold” and atoms/molecules that are “hot” in regards to molecular/atomic movement to 80% proficiency.
Students will be able to identify the region of use in the world and application of the Fahrenheit, Celsius, and Kelvin to 80 % proficiency.
Students will be able to compare and contrast the characteristics of Thermal Radiation, Conduction, and convection to 80% proficiency.
Students will also be able to diagram Thermal Radiation, Conduction, and convection to 80% proficiency .
Instruction:
Opening: The class will begin with a mini-hot air balloon demonstration made out of a trash bag, wood, and birthday candles. The students will then be instructed to diagram and explain why the balloon achieves lift.
Engagement:
Power Point Presentation on Heat, Temperature Scales, Thermal Radiation, Conduction, and Convection.
In-Class Questions:
What temperature scale do we use in the USA?
What scale does the rest of the world use?
What are the two main scales used in the scientific community?
What does a cold/hot molecule look like?
What medium does thermal radiation travel through (Trick question)?
What happens to coffee when we place it in a cold mug?
What happens to the mug when we put hot coffee in it?
Which way does the heat flow in the coffee mug system?
What happens if we put a metal rod in a fire?
What common method do we use to prevent ourselves from getting burned when we have a piece of metal in a hot medium?
Closure: The class will end with the same opening question. However, the students should be able to diagram the balloon more accurately.
Assessment:
Students will be assessed on their net-learning between the opening and closing activity. This means that if they got part x on the opening activity wrong and they got part x on the closing activity right then they receive full credit.
